The Realtek RTL8211E allows customization of the PHY LED behavior, like which LEDs are on for certain link speeds and which LEDs blink when there is traffic. By default EEE LED mode is enabled, in which a blinking LED is on for 400ms and off for 2s. This series adds support for configuring the LED behavior through device tree properties. The RTL8211E supports Spread Spectrum Clocking (SSC), which reduces clock noise that may affect other board functions. By default SSC is disabled, this series adds support for enabling it through a device tree property. Certain registers on the RTL8211E can only be accessed through a vendor specific extended page mechanism. Extended pages need to be accessed for the LED configuration and enabling SSC. This series adds helpers to facilitate accessing extended pages.
